We performed a comparison between IBM PowerVM and VMware vSphere based on real PeerSpot user reviews.
Find out in this report how the two Server Virtualization Software solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."We always recommend PowerVM to our customers; it is better than most solutions."
"The tool's performance is top-notch."
"The most valuable feature is the flexibility in terms of managing the hardware resources such as RAM, CPU, and the network."
"It's scalable. Whenever we buy another product other than hardware, it's easily integrated into the virtualization software that we download."
"PowerVM's most valuable features include swift optimisation and real-time migration."
"What I like about this solution, is that it is easy to configure."
"A valuable feature of PowerVM is a feature that is used for higher availability plus stream for posting, which is very useful. There's a flash copy feature which we are using. PowerVM itself, I know, helps us to control and manage our Oracle licensing compliance, since it is our hardware partitioning. This is very important. If you use VMware, there will be a licensing issue. This PowerVM is a hardware partitioner, which is very important for license compliance. We are happy with this solution."
"Active Memory Sharing dynamically reallocates memory of running partitions based on changing workload demands. The memory for the pool is carved out from Physical memory and is made logical memory. The said memory is not available to be assigned to partitions as dedicated memory. A min, max and desired as well as weight is assigned to the memory of each lpar to help hypervisor make a decision in case a condition where priority is to be given to a certain lapr to use the memory form shared pool."
"The most useful features are ESXi, DRS, Auto Deploy, and the Lifecycle Manager."
"We have seen a tremendous performance boost. From when we started this VMware engagement in 2016 until now, we have seen around a 70 percent performance boost. This is a good number."
"The solution has many valuable features. Virtualization is flexible and it has simple clustering. However, the most important feature is the ability to move between VMs. The vMotion features are very good."
"The most valuable feature of the solution would be the basic feature of server virtualization, we use it everywhere."
"We have removed the need for backups and going to the office at three in the morning to change a server. I do everything during my business hours. It gave me my life back."
"It's much more stable than other products. It is scalable and easy to implement as well."
"The most valuable features are the virtualization and the performance on the virtualization platform."
"I like stability and the organization of the different functions into the I#M feature which is also quite useful, quite stable."
"The cost of this solution is high."
"The hardware licensing model could be improved because the licensing model is a bit different from the standard hardware procured."
"This solution is lacking the ability to have servers act as a cluster, such as in VMware. IBM has come out with a feature similar to VMware's vCenter but it is not as mature. They need to add LPM shared-nothing feature, such as in vMotion."
"IBM PowerVM could improve the price because it is expensive."
"The interface is not user-friendly in places, so it could use some improvement."
"The licensing could be better."
"To make it a ten, I would like for them to add automation and configuration tools in order to help use the manager."
"If it could actually virtualize the entire platform it might be better. If you're having more than one virtualization technology, maybe there's a way to actually have less - one technology to run the data center and maybe one special virtualization for power. If it integrated with other platforms more effectively it might be better."
"I would like to see VMware vSphere provide a centralized patch service on the VMware level, regardless of your operating systems."
"There was a time we lost the password for the ESXi and we had to do a hardware reset. At this point, we had to fill up the ESXi from the bottom up. I am not sure if there was another solution to this problem but it took a long time."
"When I use VMware and Citrix there are conflicts."
"The technical support could improve by being a little faster."
"In the next release, I would love to have Java as a service, platform as a service, and container as a service."
"The licensing costs for the solution are quite high."
"Reporting on vCenter needs to be improved."
"The license fee could be more affordable."
